SP165(76-165mm) steel pipe manufacturing machine process is a series of steel pipe manufacturing process that builds longitudinal weld seam pipe with steel strips of certain width. It starts by uncoil and flatten the slit steel coils into steel strips. The flattened steel strips will be inserted into the forming machine and the rollers in the machine will bend the strip to a round pipe shape. The round steel pipe manufacturing machine. then be sent into the weld box where the pipe is welded by a high frequency or solid state welder. The steel pipe machine be formed to expected shape (round/ square/ rectangle etc) or size in a sizing machine. Finally the pipe will be cut to length and bundled.

2. Process flow of steel pipe machine

pipe making machine, pipe welding machine

Step 1: Uncoiler Function: support rolled plate and strip tension for steel pipe manufacturing machine, by the frame, main shaft, increases of drum, brake. There are 3 types: pneumatic, hydraulic and manual.
Step 2: Shear & Butt-welding Function: Shear the end of each strip coil, then welding them together, so that steel pipe machine can be continue production. 2 Types: Automatic & Manual
Step 3: Strip Accumulator Function: storage strip to keep continue production. 2 Types: Horizontal / Vertical Advantage: Horizontal type can be larger storage. Vertical type is much cheap and small space occupied.
Step 4: Forming Section Function: forming the tube from strip Advantage: >Advanced forming technical >One-stage molding platform >Reliable quality gear box >Siemens Beide motor
Step 5: High Frequency Welding Function: Welding the pipe , different thickness & diameter, the power of the steel pipe manufacturing process welder Our advantage: We choose the China best welder: Sanyi brand.
Step 6: Sizing Section Function: sizing the tube to precise size Advantage: >Advanced sizing technical >One-stage molding platform >Reliable quality gear box and Siemens Beide motor >High precision, low error of the pipe size
Step 7: Flying saw / Cold Saw Function: cutting the tube mill line tube to right length. Fly saw: easy to operation, low investment. Cold saw: no noise, no burr cutting precision and cross section.
Step 8: Run Out Table. Function: run out the pipe, packing the pipe for steel pipe manufacturing machine Type: Automatic or manual
